Product identity

The AddOn J9281B-AO is a one-metre passive twinax direct-attach cable with SFP+ connectors on both ends. It provides a 10 Gbps copper link for short-reach network connections between switches, servers or storage arrays.

Upgrade path

The cable replaces fibre patch cords and transceivers for rack-to-rack or intra-rack links up to one metre. The jump is worth it when latency, power draw and cost per port must be minimised and the distance stays within the passive copper limit.

Fit and alternatives

It suits builders who need a TAA-compliant, HP J9281B-compatible SFP+ DAC for 10 GbE deployments. Buyers who need longer reach, active circuitry or a different vendor qualification should look at other cable types.

Highlights

  • 1m passive DAC for short 10G links
  • SFP+ connectors on both ends for direct attach
  • Twinaxial copper construction for low latency
  • Black cable jacket for clean rack routing

Questions about this item

Will this 1 m SFP+ twinax cable fit a standard SFP+ port on my switch?

Yes, both ends use a standard SFP+ network connector that mates with any compliant SFP+ cage.

What is the correct way to seat the SFP+ connectors so the link comes up?

Insert each end straight into the cage until the latch clicks, then give a gentle tug to confirm it is locked before tightening any thumbscrews.

How often should I replace a passive twinax cable like this in a 10 GbE rack?

Passive twinax has no active components, so it only needs replacement if the cable jacket is kinked, the connectors are bent, or link errors appear.
